` `RAYMOND Gr. MOORE, `F BRIDGEPORT, CONNECTICUT, ASSIGNOR T0 THEBASSICK` COM- IANY, OIF` BRIDGEPORT, CONNECTICUT l LATCH LApplicationmed June 22,`-

The present invention relates to an 'im` proved latch, particularly forautomobile doors and of the type having an inside and an outsideoperating handle, and in which the outside handle is adapted tobelatched against operation by manipulation of the inside handle. Thelatch is especially adapted for use upon doors of closedcars, beingapplied to all but one of the doors, and which latter is adapted to belatched from the outside. I particularly propose to provide an outsidehandle roll-back adaptedy to operate upon the latch bolt through anintermediate retracting member, and an inside handle rollback adapted tooperate upon the latch` bolt through a'retracting and latching membercooperatively related yto said. intermediate member, and which isadaptedupon manipulation in one direction to retract the latch boltthrough actuation of said intermediate member, and in the otherdirection to latch said intermediate member against operation by theoutside handle roll-back. l

Another object is to provide a latch bolt adapted to have freeretracting movement in the latched relation of the outside handle,either by manipulation of the inside handle in bolt retracting directionor lby pressure Y, applied against the nose end of the bolt, and

further to provide a latchconstruction in which the roll-baclrs'may beplaced at any desired points, without changing their main combinativerelation, or materially alter- I; ing the design ofthe parts, therebyadapting the main parts of the latch to use upon va-y rions car doors,in which the positions of the handles are diie'rently arranged; vand-inthe illustrated embodiment, I propose to provide a remote control insidehandle roll-back adapted to be placed at any desired point on the doorframe. With the above and other objects in View, an embodiment of theinvention is shown in the accompanying drawings, and this em bodimentwill be hereinafter more fully described with reference thereto, and theinvention will be finally pointed out in 'the claims.

vSimilar reference characters indicate corresponding parts throughoutthe several {igures of the drawings. j

Referringto the drawings and more particularly to Figs. 1 to 6 thereof,the embodiment ofthe invention shown therein comprises asheet 'metalframe or base plate 10 `having a face ange 11 bent therefrom at koneend, within which a rectangular latch bolt opening 12is provided.`Flanged lipj portions 13 and 14,'formed of the metal out from saidopening are bent outwardly in parallel spaced relation to each other toform bearings for the latch bolt; the flange 14 being Hush with the baseplate 10.

The latch bolt comprises a nose portion 15, riveted at 16 to a sheetmetal bolt plate or bar 17. guided near its inner end between guide lugs18 and 19 struck and bent upwardlyv from the base plate, a coil spring20, mounted upon the base plate by means of a clip 21, having its endengaged in a recess 22 in the upper edge of the bolt and normally Theoutside handle roll-back 28'has its hub 29 rotatably engaged inapertures 30 and 31 formed in thebase and cover plates adjacent theflange l1, and is adapted to retract the latch bolt through anintermediate retracting slide bar 32 engaging the base plate andprovided at its forward end with an upwardly bent flange 33against-which the roll-back engages. A projecting lug 34 is provided vatthe upper edge of the intermediate retracting har which engages in therecess 23 of the latch bolt against the rearward wall thereof, the latchbolt spring 2O being adapted to normally7 press the bolt forwardlyagainst theV roll back, therebv limiting` the projection of the bolt andyieldably retaining vthe roll back in its normal position against ktheflange 11. The elongated recess 23 however, permits free retractingmovement 'of the bolt, through pressure applied to its nose end as in'closing the door, independently of the retracting'bar and theroll-back.

The intermediate retracting bar is guided in its longitudinal movementat its forward end by engagement of its upper edge, forwardly of the lug34, with the lower edge of the latch bolt, and bv engagement of itslower edge with a guide flange 35 struck'and bent from the base plate.and is guided at its rear` ward end between the guide flange 19 engaging its upper edge. rearwardly of the lug 34, and a similar guideliange 36 bent and 'struck from the base plate and engaging its loweredge.` l

In superimposed relation to the retracting bar 32 there is provided abar 37, also guided iny its longitudinal movement by the lower' edge ofthe latch bolt and the flanges 35, 19

and 36, and projecting rearwardly of the base' plate, where it ispivotally connected at 38 to one 'end of a link 39 (Figs. 7 to '10)connected at its other end to the remote control inside handle roll-back40, placed at any suitable point upon the door frame.' This bar 37 isoperatively connected to the intermediate retracting bar 32 by means ofa lug or flange 41 struck up from the bar'32 and engaging an elongatedslot 42 in the bar 37, this connection being such that retractingmovement of the bar 37 retract-s the intermediate bar 32, therebyretracting the bolt, while retracting movement ofthe bar 32, throughop-' The intermediate retracting bar and the outside handle roll-backare adapted to be locked against movement by movement of the bar 37 inthe opposite direction to its retracting movement, and for this purposea transversely reciprocating stud 43 is mounted in a transverse slot 44in the base plate, and engages slots 45 and 46 respectively provided inthe bars 32, and 37.

rlhe slot 45 is of right-angular shape, its longitudinal portion beingrelatively elongated and adapted to permit normal retracting movement ofthe bar 32 in the upper or inoperative position of the l stud, (Fig. 8)while its transverse Aportion is co-eXtensive with the' slot 44 in thebase plate and is adapted to latchjthe bar 32 against movement in thelower or operative position of the stud.

The slot 46 in the bar 37 is of obtuse angular shape, its longitudinalportion being coeXtensive with the longitudinal portion of the slot `45and adapted to permit of retracting movement in the upper position ofthe stud (Fig. 9), while its angular or camming portion extends to alpoint longitudinally aligned with'the lower end of the slot 44, so thatupon movement of the bar 37 ina reverse direction to its n.normalretracting movement the stud is cammed downwardly in the slot 44, atthesame time engaging the transverse portion of the slot 45 of theintermediate retracting bar 32 and latching it against operation, sothat retraction of the bolt by means of the outside handle roll-back isprevented (Fig. 10). l

In order to unlatch the bar 32 the inside handle is merely turned inretractingdirection. the initial movement of the bar 37 in retractingdirection c'amming the stud 43 to its upper or inoperative position inline with the longitudinal portions of the slots 45 and 46, and thecontinued movement causing retraction of the intermediate retracting bar32 through abutment Vof the end ofthe slot 42 with the lug 4l, andconsequent retraction of the bolt.

I have illustrated and described a pre-I ferred and satisfactoryembodiment of the invention, but it will be obvious that changes may bemade therein, within the spirit and scope thereof, as defined in theappended claims.'

Having thus described my invention, what I claim and desire to secure byLetters Patent is l. In a latch, a latch bolt, retracting means for saidbolt including inside and outside manually operable retracting means, anintermediate retracting member cooperatively related to said bolt andinterposed between said inside and outside retracting means and saidbolt and adapted to be moved in bolt-retracting direction by saidretracting means, a reciprocating member adapted to be actuated by saidinside retracting means and connected to said intermediate retractingmember to impart retracting movement thereto upon movement inbolt-retracting direction, said intermediate retracting member having alatching slot, said reciprocating member having a camming slot, andtransversely movable latcliing means having transverse movement onlycooperatively engaged in said slots and adapted upon movement of saidreciprocating member in nonbolt-retracting direction to be cammed bysaid camming slot into latcliing relation in said latching slot.

2. In a latch, a latch bolt, retracting means for said bolt includinginside and outside manually operable retracting means, an intermediateretracting member cooperatively related to said bolt and interposedbetween said inside and outside retracting means and said bolt andadapted to be moved in bolt-retracting direction by said retractingmeans, a reciprocating member adapted to be actuated by said insideretracting means and connected to said intermediate retracting memc berto impart retracting movement thereto upon movement in bolt-retractingdirection, said intermediate retracting member and said reciprocatingmember adapted to have longitudinal movement in parallel relation tosaid bolt, said intermediate retracting member having a slot including alongitudinal portion and a latching portion, said reciprocating memberhaving a slot including a longitudinal portion and a camming portion,and transversely movable latching means having transverse movement onlycooperatively engaged in said slots and adapted upon movement of saidreciprocating member in non-bolt-retracting direction to be cammed bysaid camming portion into latcliing relation in said latching portion.
